Manos: The Hands of Fate is a horror movie about a young family being trapped in a lodge in the desert, while its owner summons the evil demon Manos. Conventional criteria of quality can't really be used for describing the movie's features, as there are countless apparent flaws in the production, e.g., the plot, the acting quality, and the editing. However, in a way, all these problematic technical aspects sum up to a fascinating experience that doesn’t bears any resemblance to what most come to expect from movies in general. Therefore, it can be watched for escapist entertainment, mocking the low quality or even for technical analyses. Ultimately, as a movie, Manos: The Hands of Fate, can only be recommended as a prime example of what not to do.

Never since Billie Sol Estes has a Texas fertilizer salesman have the audacity to sell an epic pile of shit to the unwashed masses.

If you've watched Manos, you are probably in a deep funk... and will be for some time. Perhaps the rest of your life if you don't take remedial action.
I think the only way to clear your palate of this movie is to watch it again as Joel and the Bots of MST3K take it apart.
There is a web site with an interesting interview of one or more of the people who were involved in the making of Manos:

Some movies are just plain bad, some are so bad that they're good, but Manos transcends all that! Ed Wood is Hitchcock or Bunuel or D.W. Griffith in comparison.
Rating: -5 Stars

Yaz flute AND wrestling women in diapers!! Does it get any better? Er, I mean, worse?!!! I want my one hour of life back after watching this complete peice of crap movie. Not cool. Not even as a very bad movie is this movie any good. Burn the master reels and all copies....

This make an Ed Wood film look like MGM gloss! I honestly think its the WORST movie I've EVER seen, and that's saying a lot! LOL

Wow, I can see why this fell out of copyright. Bad "acting," bad script, terrible editing. But it does have a five-girl catfight in negligees, although they all appear to be wearing Depends, and it does have death by hot babes in negligees, although it looks more like they're applying a facial massage.
Six wives, but only three have speaking roles; the others only shake their heads and cat fight.
Mike must be the dumbest husband of all time, and he has a loaded gun. "Mike, I want to go." "Okay, we'll leave. We'll hide in the desert; someone will help us."

Somebody must have been trying to make a really bad movie, but they screwed that up and made the worst pos movie ever.

Wow, it's original music!!! :)

Was this flick the result of monumental incompetence or bad drugs? I can't believe it wasn't both. Anything you might imagine could be wrong with a movie is wrong with this one, plus much, much more. Beyond bad it is excruciatingly bad, and just when you think it couldn't possibly get any worse, it falls off another cliff. Anyone who claims Ed Wood is the world's worst director should be condemned to watch this cinematic catastrophe a dozen times. Nevertheless it grudgingly gets three stars because it does provide some entertainment in the form of sick fascination, and the spastic caretaker, Torgo, is hilarious - unintentionally of course.
Kids, stay clean and sober, or this could happen to you!
